When it comes to the Nets, good medical news usually means the lack of a trip to an emergency room.

Really good news might be considered a quick return from the infirmary.

So Lucious Harris shooting baskets in the morning might be considered really good news.

“I’d say maybe three weeks and I’ll be back playing,” said Harris who was sidelined at the start of training camp because of a hernia requiring surgery.

“They’ve got me running in the pool, doing ab [abdominal] work in the pool, just moving.”

Among the Net weaknesses is a decided lack of perimeter shooting, something Harris can help alleviate. Coach Byron Scott wants Harris back but he isn’t as optimistic as the player as to the timetable.

“Three weeks? It might be closer to four with the conditioning he has to go through,” said Scott. “Three weeks is conceivable, but I think it’s more like four.”
